Abstract (en)
[origin: EP0577428A2] The present invention reproduces an input image of half the normal resolution with respect to the vertical and horizontal directions in high picture quality by processing a coded bit stream of a normal resolution. Difference signal (mismatching error signal) representing the difference between a predicted image of the normal resolution and a predicted image of a half resolution with respect to the vertical and horizontal directions is coded and the coded difference signal is transmitted. When producing the predicted image, image data is subjected to motion compensation according to a specified prediction mode. <IMAGE>
